Convergent evolution of extreme snout elongation in deep-sea fishes reveals constrained trajectories

Phenotypic extremes are scattered across the Tree of Life, suggesting that evolutionary constraints often limit their emergence. Yet striking departures from standard body plans, such as elongate snouts, have evolved convergently across deep time. We investigate extreme morphologies in two distantly related deep-sea fi...

Selection, constraints, and contingency drive mosaic patterns of evolution during the carangarian adaptive radiation

Adaptive radiations generate remarkable morphological diversity, yet traits often diversify at different rates and modes, producing mosaic patterns of evolution. Modularity, the semiautonomous organization of traits, can shape how selection and constraint interact during these radiations, but its macroevolutionary cons...
